- •
A new hybrid method is introduced to locate a delamination in composite laminates.
- •
The experimental case considered mimic a practical application very closely.
- •
The method does not need information from the pristine specimen.
- •
The method uses only eight piezoelectric wafer transducers thus quite economical.
- •
The method can detect any breathing damage which can induce contact nonlinearity.
